SUMMARY STEPS
1. configure terminal
2. Use one of the following:
3. mls qos srr-queue input threshold queue-id threshold-percentage1 threshold-percentage2
4. end
5. show mls qos maps
6. copy running-config startup-config
DETAILED STEPS
Command or Action
Step 1
configure terminal
Example:
Switch# configure terminal
Step 2 Use one of the following:
• mls qos srr-queue input dscp-map
queue queue-id threshold
threshold-id dscp1...dscp8
• mls qos srr-queue input cos-map
queue queue-id threshold
threshold-id cos1...cos8
Example:
Switch(config)# mls qos srr-queue
input
dscp-map queue 1 threshold 2 20 21
22 23 24 25 26
Step 3
mls qos srr-queue input threshold
queue-id threshold-percentage1
threshold-percentage2
Example:
Switch(config)# mls qos srr-queue
input threshold 1 50 70
• mls qos srr-queue input dscp-map queue queue-id threshold threshold-id dscp1...dscp8
• mls qos srr-queue input cos-map queue queue-id threshold threshold-id cos1...cos8
Purpose
Enters global configuration mode.
Maps DSCP or CoS values to an ingress queue and to a threshold ID.
By default, DSCP values 0–39 and 48–63 are mapped to queue 1 and threshold
1. DSCP values 40–47 are mapped to queue 2 and threshold 1.
By default, CoS values 0–4, 6, and 7 are mapped to queue 1 and threshold 1.
CoS value 5 is mapped to queue 2 and threshold 1.
Assigns the two WTD threshold percentages for (threshold 1 and 2) to an
ingress queue. The default, both thresholds are set to 100 percent.
Each threshold value is a percentage of the total number of queue descriptors
allocated for the queue.

• For queue-id, the range is 1 to 2.
• For threshold-id, the range is 1 to 3. The drop-threshold percentage for
threshold 3 is predefined. It is set to the queue-full state.
• For dscp1...dscp8, enter up to eight values, and separate each value with
a space. The range is 0 to 63.
• For cos1...cos8, enter up to eight values, and separate each value with a
space. The range is 0 to 7.
• For queue-id, the range is 1 to 2.
• For threshold-percentage1 threshold-percentage2, the range is 1 to 100.
Separate each value with a space.
